OpenBSD/amd64

OpenBSD/amd64 runs on AMD's Athlon-64 family of processors in 64-bit mode.
It also runs on processors made by other manufacturers which have cloned
the AMD64 extensions. (Some Intel processors lack support for important
PAE NX bit, which means those machines will run without any W^X support --
it is thus safer to run those machines in i386 mode).

Note that OpenBSD/i386 also runs on these
processors, but in 32-bit mode.

X Window System support is available for most graphics cards, using
the X.Org server. As with other free operating systems it is highly recommended
that Nvidia cards are avoided since this vendor continues to show tremendous
resistance towards releasing information that would allow X.Org to support their
hardware properly.

CD boot
The CD provides an El Torito no-emulation boot image
that includes almost all OpenBSD drivers.
This also includes minimal USB support (storage devices and keyboard).
For the latest list of drivers available on this image, take a look at the
RAMDISK_CD
kernel configuration file.

Floppy A (floppy54.fs)
This 1.44MB floppy image contains the most common drivers.
It is designed to cover the most typical PC. As a general rule, you will
find that the missing drivers are ones which need large microcodes to run,
such as for rare SCSI cards, gigabit ethernet cards, or RAID devices.
